The detailed evidence from the Book of Allah includes Allah's description of the believers, whom He calls "Worshippers of the Most Gracious", saying: "And those who do not witness falsehood and if they pass by ''Laghw'' (evil play or evil talk) they pass by it with dignity". [25: 72]. This ayat is very clear and explains the dislike of Allah as regards to such festivities........................................!!!!
Rasoolullah (Sall Allah u Alaihi wa Sallam) said: 'You will follow the ways of those nations who were before you, span by span and cubit by cubit (i.e. inch by inch) so much so that even if they entered a hole of a zab (a kind of lizard) yo...u would follow them.' We said, 'O Allah's Apostle! (Do you mean) the Jews and the Christians?' He said, 'Whom else?'
